MAX6358SVUT+T

Overview

The MAX6358SVUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two input voltages with thresholds of 3.08 V and 4.63 V. The device features an active low, open drain output type and includes a manual reset function alongside a watchdog timer. It provides a reset delay time of 180 ms and operates within a supply voltage range up to 5.5 V. The component is housed in a SOT-23-6 package.

Feature Summary

• Dual voltage monitoring with factory-set thresholds for system reliability
• Integrated watchdog timer with defined startup and normal timeout periods
• Debounced manual reset input compatible with TTL/CMOS logic levels

Applications

• Microprocessor power supply supervision
• Embedded system voltage monitoring
• Industrial control unit reset management

Procurement Notes

Verify the exact suffix configuration against the manufacturer's current part numbering guide, as variations exist within the MAX6358 family. Confirm availability status through official distributors, as specific variants may be discontinued or subject to limited supply constraints. Ensure the selected package matches the target PCB footprint requirements prior to ordering.

Selection Notes

Select this component when precise monitoring of two distinct voltage rails is required. The open-drain output allows for flexible interfacing with various logic families. Consider the integrated watchdog functionality for applications demanding automated fault recovery without external components. Verify that the threshold voltages align with the specific power rail specifications of the target design.

Part Context

This part belongs to the MAX6351-MAX6360 series of microprocessor supervisors. These devices are designed to improve system reliability by providing multiple reset voltage outputs in a compact SOT-23 package. The series supports both dual and triple voltage monitoring configurations, offering a cost-effective alternative to discrete supervisory solutions.
